为了实现小口径弹药的一维弹道修正,文中提出了一种新型的增加阻力式弹道修正机构。利用ADAMS软件对其机构运动特性进行了仿真;利用FLUENT软件对装有该机构的某榴弹进行了气动特性仿真;利用质点弹道方程程序估计了其修正量。仿真结果表明这种阻力修正机构展开速度快,增阻效果明显,修正量满足需要。为该机构的实际应用提供了数据参考。

In order to achieve one-dimensional small-caliber ammunition trajectory correction, this paper proposed a new mechanism which correct trajectory by increasing resistance. The ADAMS software was used to its mechanism motion characteristics. The FLUENT software was used to simulate aerodynamic characteristics of a grenade equipped with this mechanism. The particle trajectory equation procedure estimates its correction procedures. Simulation results show that this correction mechanism unfolds faster; increasing resistance force is obvious, fixed distance meets the need. The practical application of the institution provides data for reference. This paper provides data for reference in practical application.
